Well, the next dry day we get here, I'm gonna clean the engine. I have to do it before Friday.

I'm taking the car in for an oil change and want them to have a good look at it with a clean engine so they can better diagnose the problem.

I've heard the old "while there in there" working on the head gasket, might as well do the valve guide seals???

Any thoughts on that?

What about timing chain?

Anything else? I don't want to have to go back in there for another 100k-150k miles if possible.
